To take your information from Hollywood, you would think that Piranhas are just pack hunters, permanently hungry and roaming around looking for a meal to attack.
In short, most Piranhas are omnivores and eat both meat and fruits, as well as seeds, insects, fish and plant matter. There are a few species that are more aggressive towards meat, but it’s equally true that there are some specifically herbivores amongst the Piranha. The Red-Bellied Piranha is the most aggressive and survives well on normal vegetation as well as fish. Large animals can be stripped to the bone as long as they are already deceased. Piranhas are natural scavengers.
What Do They Eat in the Wild?
The Piranha is sometimes referred to as opportunistic carnivore. It feeds on aquatic and land animals in the water. In his visit to the South American jungle president, Teddy Roosevelt reported seeing a fish that could tear a whole cow to the bones within minutes.
The Hollywood movies have not done any justice to the Piranha fish. It is portrayed as a man-eating creature with an uncontrolled ferocity. It is true that a Piranha school has a huge appetite for flesh if hungry, but they rarely attack large animals, if ever if they are alive. From a carnivorous point of view they eat ..
- Small fish
However, as some are herbivores, and even the the Red-Bellied is omnivorous, they also eat
- Plant matter
Piranha take bites of the fins of other fish that pass nearby and show signs of cannibalism during the dry spell. These fish do not attack humans unless they think that they have died or are incapacitated. However, can cause minor bites to swimmers during the season when there is a scarcity of food, but this is mostly when their nests are threatened when breeding.
Piranha are generally an omnivorous fish by nature. Despite their muscular jaws and sharp chiseled teeth they love the vegetation as much as they love their meat.
They will feast on fallen fruits, seeds, algae and seaweeds they are suited to respond to the splashing of water and noise made by falling fruits. The Amazon has dense plant growth which supplies food for the Piranha fish.
How Often Do Piranha Eat
Piranha in the wild eat whenever there is the availability of food in their ecosystem. In an aquarium they will feed once or twice in a day. Juvenile or young Piranha will feed two to four times a day.
Feeding habits vary depending on what you feed your fish, overfeeding your fish will result from increases in waste in your water making it necessary to change the water regularly. Too much waste makes it necessary to maintain the filter system at all times.
Providing a proper diet to Piranha increases the lifespan of your fish and boosts their immunity.
When Do Piranha Eat?
Foraging methods vary in species of Piranha and within each stage of development of the fish. During the day, especially at dawn smaller fish search for food while larger fish will look for food late in the afternoon and early in the evening.
This fish show signs of communal feeding especially during the dry season when there is a shortage of food or when they are triggered by noise, splashing or blood in the water. During feeding frenzies, these fish show signs of communication as the fish on the inner parts of the shoal give way for the ones on the outer parts of the school to have a bite too.
Frenzies occur at any time of the day as long as the fish are triggered by a potential meal, and especially if driven by hunger.
